Specification of Letters Patent.

Application led July 22, 1909.

4 The oiler which is the subject of the present invention is designed more particularly for automobiles, and consists in the novel construction and arrangement of parts to be hereinafter described and claimed.

It is Well known that it is a diilicult task to oil some parts of an automobile, especially the differential and the transmission gearing thereof, not only on account of the inaccessible location but also by reason of the consistency of the lubricant usually employed, which is heavy and must be forced to reach the desired places.

It is the object of the present invention to facilitate the forced oiling of the different parts of the automobile and also to provide an oiler Which is cleanly in operation and in which Waste ofthe lubricant is eliminated. i

Another object. of the invention is io providean oiler which can be easily lilled, and which Will hold a suiiiciently large supply of lubricant to oil the machine several times Wit-hout refilling.

' main body or reservoir of the oiler, which is preferably cylindrical in form, and has revniovably connected to one of its ends, by

screw'threads 1 or some other form of joint, n tapcred portion or funnel 6, terminating at its smaller end in a cylinder 7, the diameter of which is less than the diameter of the main body 5. The opposite end of the main body is closed by a screw Acap 8. The outer end ofthe cylinder 7 has a threaded opening 3 to receive a spout or nozzle 9, which is also removably connected to the cylinder, and which may have a terminal curve as shown.

In the cylinder` 7 Works a phuiger 10 to which an operating stem 11 is connected, this stern extending through the main body 5, andthrough an opening in the cap 8, to the outside thereof, its outer endfbeing fitted with a knob or'handle 12. The cap; has a lstullingbox 13 throughfwhich the stem 11 by drawing upward on the knob so t Patented Mar. 21, 1911.

extends, said stuffing box being closed-by a gland nut 14. On the inner face of the cap and extending into the main body 5, is a tubular guide 15 of considerable length, through which the stem v11 also extends, and which serves to guide the same and cause the plunger 10 to enter the'cylinder 7.

The operation of filling the oiler is as' follows The plunger l0 is Withdrawn from thecylinder 7 into the main body 5, possibly as far as the guide 15, and the funnel V6 is then unscrewed and removed from the main body, after Which the latter is filled with oil to its capacity. The funnel 6 is then replaced and the oiler is ready for use.

Inuse, the oiler is held With the cylinder 7 lowermost which'causes a thin lubricant to flow into and through the funnel and thence into the cylinder until it fills the same, and it is forced out of the cylinder into and from the nozzle 9 by operating the plunger 10. In this operation the knob 12 is'pressed upon to slide the stem l1 longitudinally through the guide 15, and the lengt-h of the latter and its axial disposition in true alinement With the cylinder 7 Acause the plunger to move down the center of the body, through the funnel, and into the upper end of the cylinder behind the lubricant cupped therein; after which further pressure on the knob ejects the lubricant forcibly from the cylinder. After all of the charge therein has been ejected, the cylinder may be refilled Without removing the oiler; and this is accomplished at the plunger is drawn out of the cylinder for sufficient distance to allow the lubricant to a close place or a rather thick oil is used as a lubricant, the inozzle can be removed and the lubricant discharged directly 4,from the cylinderj.

An oiler constructed as herein described is easily filled and operated, it is simple in structure, is clean in its operation, and there is no waste of the lubricant.

As above stated, the guide 15 is of con-I siderable length, although'I do not Wish'to be unncessarily limitd in this respect. It has three important functions; first 1t serves as a guide for the stem so that in the forward movement of the plunger the latter is directed straight into thej cylinder, next itserves as a stop when the plunger is retracted and for this purpose its inner end should be farther remote from the inlet end of the cylinder than the length of the plunger itself, and finally it serves as a shield to prevent the escape of the lubricant through the stuiiing box 13 in case the oiler should be stored by resting it on its larger end because in such position it is obvious that the llubricant. would settle against 'the cap 8 around the ide 15.

What is c aimed is The herein described oiler, the same comprising a cylindrical body, a funnel detachably connected at its larger end to one end of the body,'a cylinder connected at one end to and communicating with the smaller end of the funnel, and a nozzle detachably c011- nected to the other end of the cylinder; combined with a cap removably closing the opposite end of the body, a long guide secured to the cap and extending into the body di rectly toward the axis of the cylinder, a stem slidably mounted through said guide and having a handle at its outer end, and a plunger on the inner end of the stem slidably and removably fitting within said cylinder and of less lengththan the distance between the inner end of the latter and the adjacent end of the guide.

In testimony that I claim the foregoing as my own, I have hereto aixed my signature in the presence of two witnesses.
